NAME¶aptitude-robot-session - call aptitude-robot non-interactively
DESCRIPTION¶aptitude-robot-session is a helper script meant to be run from cron or init scripts. It will call aptitude-robot with some options suitable for non-interactive use. It will also redirect all output (STDERR and STDOUT) to LOGFILE defined in "/etc/default/aptitude-robot".
CONFIGURATION¶There are a few configuration options that can be defined in "/etc/default/aptitude-robot".
- the name of the file where all the output of aptitude-robot is collected. Defaults to "/var/log/aptitude-robot.log"
- the name of the file where the session log is accumulated. aptitude-robot-session will append its PID to this file in order not to overwrite a log file left over from a crashed earlier invocation. If aptitude-robot-session finishes properly it will append the session log to LOGFILE and delete the session log.
- optional command invoked with the session log as the only argument at the end of an aptitude-robot-session run. This can be used to file reports to monitoring systems or support mail addresses.
- file size limit in blocks for the session log. This prevents endless loops
if a package installation continues to ask the same question for which no
terminal is available to provide an answer.
But be aware that this limit also affects _all_ daemons started or restarted during the aptitude-robot-session run, including e.g. the OpenSSH daemon which again will propagate the limit to its remote login sessions. Use with care.
- a command that is run at the end of a successful aptitude-robot-session. E.g., use it for apt-get clean.
EXIT STATUS¶aptitude-robot-session exits with 0 on success, 1 if dpkg is locked, 2 if apt failed to fetch some APT repositories.
